The book of Exodus has many themes, but the focus here is on the freedom of God's people. They were enslaved for 400 years for absolutely no reason. They worked tirelessly under the hot Egyptian sun, day in and day out. Most importantly, they remained faithful to God whom they knew would deliver them from such a terrible fate. Through Moses (see Summer collection), the Hebrews were led out of Egypt and eventually to the Promised Land, however, Pharaoh did not give up without a fight. He was tested and tried many different times until he had finally had enough. Even after he released the Hebrews, he ended up chasing after them to try to get them back but did not succeed.
 
The parallel here is that we have a community that has been oppressed for years, centuries even. Once freed from slavery, there were still obstacles in their path that tried to keep them down or "get them back" under oppression. This group is still not completely free, but they are slowly breaking off the chains that are holding them down. There is an institutionalized Pharaoh that needs to just let them go and be free. What will it take for "Pharaoh" to let those people go?
